I have a set of Infinity Kappas in the front doors now. I also am using a PPI amp to run them. They sound GREAT in the Bonneville. Although, if you still plan on using a stick (or low powered) deck they may be a little overkill.

I know my SSEi has components, but both speakers are in the lower door. I placed my tweeters on the a-pillar but may be moveing them to the top of the door handel in the near future. I placed the crossover box where the factory tweeters were and kept the factory speaker covers. Same basic layout could be used in an SE if there is only a 5-1/4 in the door.

Infinity Reference component woofers with Infinity Kappa Perfect tweeters mounted at the top of the handle and Bose sharkfin tweeters (from a Grand Prix GTP) at the front lower corner of the 1/4 window. I placed the crossover in the "pocket" on the backside of the door panel, using double-sided tape to keep it from moving.
